To be fair, it is actually dangerous, especially with heavier doors. If one is simply competent and mechanically inclined, you figure out that you need to put the door up and tie it in place to take tension off the springs.

But oh my god, there are stupid people out there. And no one wants to be liable because some idiot couldn't be safe while working with large, powerful springs and a metal garage door/gate that wants to fall back down.
